But this isn't the peanuts and pretzels served in coach. United Airlines shared an image of the cookbook featuring a recipe for "coconut soup with sambal oelek chicken" with the Free Press.

According to the United Airlines shop, the $29.99 cookbook features over 40 recipes from United's executive chefs and chefs from The Trotter Project, which works to aid young chefs in the culinary and hospitality fields.

On its website, United said it's "excited to be the official airline of The Trotter Project," bringing gourmet options for United Polaris business class passengers and premium transcontinental service flyers, plus new dishes for international economy dining.

"A portion of proceeds (for the cookbook) will be donated to The Trotter Project to continue its mission of inspiring the next generation of culinary professionals," a United spokesperson said Monday in an email.

As Travel + Leisure notes, other airlines have also ventured into cookbooks: Southwest Airlines published "Feel the Spirit, Savor the Fare" in 2006 and Delta put out a book of recipes compiled by flight attendants called "First-Class Meals" back in 1987.
